Our Beloved Prophet Mohammed (sallallahu `alayhi wasallam) said to his uncle (father’s brother) Sayyiduna Abbass (may Allah be pleased with him) Oh uncle shall I not give you Shall I not grant you Shall I not award you Shall I not do mercy on you When you do 10 things Allah will forgive your sins: of the future and of the past; new and old; those you have forgotten and those you did knowingly; big and small; hidden and revealed. Then he (sallallahu `alayhi wasallam) explained and taught the way to pray Salatul Tasbih and then said if you can pray this salah once a day, if you can not pray once a day then every Friday, and even if this is not possible then once a month and even if this is not possible then once a year and even if this is not possible then at least once in a lifetime (Abu’Dawood & Tirimzi)

WHEN TO PRAY:
This salaat (namaz) is offered in four rakat at a time and can be read in any part of the day and night besides Zawal and Sunrise and Sunset makrooh times, keeping in mind the forbidden times for performing Salat (namaaz). It is an excellent practice during the mubarak nights of Ramadhaan and on any other auspicious night.

METHOD:
The following tasbih is recited seventy-five times in each rakat totalling 300 in the 4 raka`ats.

The method of this salah is as follows:
After beginning the salah by saying Allah-u-Akbar recite the thana ', Sura al-Fatiha and a Sura followed by the above tasbih 15 times.

Then go into Ruku and after reciting the usual tasbih for ruku` recite the above tasbih 10 times.

After standing up from ruku` recite the usual Rabbana Lakal Hamd and thereafter recite the tasbih 10 times.

Then go into Sajda and after reciting the usual tasbih for sajda recite the above tasbih 10 times.

Then sit up from sajda and recite the tasbih 10 times between the two sajdas.

Thereafer go into sajda again and after reciting the usual tasbih for sajda recite the above tasbih 10 times.

Then sit after the 2nd sajda (i.e. before standing up for the second rakat) and recite the tasbih 10 times.

This adds up to 75 times in one rak`ah. Do the same for the remaining 4 raka`at.

POINTS TO REMEMBER:

2) Do not count on fingers or by holding a Bead Tasbih in hand. It is Makruh.

3) You may count by pressing the fingers as a reminder. For example, if you are in Ruku. You may press small finger of your right hand first for the first count, then the finger next to it for second count, then the middle finger for third count, following this method until you reach the thumb. Then count back, including the thumb of the right hand again, in the same way to the small finger of right hand which will give you an exact count of ten. Use the same method in Qayam, Sajdah and Jalsa.

4) If missed a count then make it up in the next posture. For example if forgot to recite Tasbih after Surah in Qayam. Then you may recite Tasbish 20 times instead of 10 in Rukuh after "Subhaana Rabbiyal Azeem". Missed Tasbih cannot be recited in Qayam after ruku and Jalsa between Sajdah. If you missed the Tasbih in Ruku then recite 20 in the first Sajdah instead of the Qayam after rukuh. Similarly if missed the Tasbih in first Sajdah then do not make it up in Jalsa. Instead recite missed tasbih in the second Sajdah. If Tasbih has been missed in last sajdah of second or fourth Rakah then you can recite the missed ones before Attahiyat in Qaidah.

5) If you miss a wajib in Salah and have to do Sajdah Sahaw. You dont have to recite Tasbih in Sajdah sahoo, since the 300 count has been established. But if you had missed Tasbih in any of the postures and remember it now, then you may recite the missed Tasbih in Sajdah Sahoo now..
